Measurements of chloroplast permeability for the Arabidopsis thaliana wild type and atpip1;2-2 mutant

Chloroplast permeabilities were determined using the same principle as described for Table 1; shown are means ± SDs (n=4 different chloroplast isolations from four different plants)

Chloroplast permeability	Wild type	atpip1;2-1
${\text{P}}_{{\text{CO}}_2}$ (m s–1)	2.27 × 10–4±6.6 × 10–5	1.02 × 10–4±5.9 × 10–5
${\text{P}}_{{\text{HCO}}_{{\text{3}}^{-}}}$ (m s–1)	1.0 × 10–8±5 × 10–10	1.0 × 10–8±7 × 10–10
